通过空间计量模型考察生产性服务业发展模式与制造业集聚的空间溢出效应后发现:生产性服务业专业化水平及多样化水平与制造业集聚呈倒U型关系,同时城市化水平会对服务业发展模式与制造业集聚关系产生影响。分区域模型研究发现,生产性服务业对制造业全要素生产率影响因区域经济发展水平、产业层次、要素禀赋等因素有所差异,东部地区制造业全要素生产率与生产性服务业呈线性关系,适合选择多样化发展模式;中部地区呈倒U型关系,现阶段中部地区生产性服务业更适合选择多样化发展模式;西部地区生产性服务业发展水平与制造业全要素生产率呈正U型关系,生产性服务业专业化和多样化发展都将促进制造业全要素生产率提升。  相似文献

This paper aims to investigate the crisis linkage and transmission channels within the housing, stock, interest rate and the currency markets in the U.S. and China in the past decade since the 2008 Subprime Mortgage Crisis. Two hybrid models, namely the SWARCH-EVT-Copula and the Bivariate SWARCH-EVT models, are proposed and applied in order to take into account (A) the high/low volatility regimes, (B) the interdependence structure inherited from the joint tail behaviours, as well as, (C) the risk spillover dynamics among financial sectors during market turmoils. We empirically show that the housing and stock markets share the strongest linkage and play central roles in the spreading of shocks. With a highly integrated system, the American financial sectors are under greater exposure to risk contagion and systemic risk during crises than the Chinese markets. Nevertheless, the exchange rate risk of Renminbi remains at an intensive level since its “crawl-like arrangement” and leads to increasing co-movements in the stock and interest rate markets since 2014.  相似文献

以制造业上市公司为样本,探讨社会资本能否抑制僵尸企业对健康企业创新的挤出效应。结果显示:僵尸企业每增加1%,健康企业的发明专利数降低0.41%。僵尸企业的创新挤出效应大部分由非国有企业承担,国有企业的创新并未受到影响。健康企业通过积累不同类型的社会资本来抑制僵尸企业对其创新造成的挤出效应。非国有健康企业的连结型社会资本对创新挤出效应的抑制作用最强,结合型社会资本的作用次之,桥接型社会资本的作用最小。  相似文献

The distributional effects of a major air regulation in the United State in 2015 were analyzed using Berliant and Strauss Index Numbers, a set of theoretical and empirical equity metrics, and reduced‐form models that estimate the mortality effects of air pollutant emissions and their source contributions. By viewing the effects of pollution on human mortality as an implicit tax, we found progressivity in 54% to 56% of vertical comparisons and inequity in 92% to 94% of horizontal comparisons. The introduction of the proposed policy made 58% of vertical comparisons more progressive and was equitable to 70% of horizontal comparisons.  相似文献

This article examines the role of small- and medium-sized multinational enterprises (MNEs) in the dynamic development of global production networks (GPNs) in the maritime industry. It studies the dynamism between subsidiaries of Norwegian maritime firms and regional actors and institutions in the Greater Shanghai Region of China from the perspectives of the subsidiaries. It argues that strategic coupling, recoupling and decoupling are partly the results of regional selection mechanisms. However, in the cases where the subsidiaries are embedded within the host region, the strategies and behaviour of MNEs are of decisive importance for the dynamic development of GPNs.  相似文献

Reducing dependence on fossil fuels by decreasing energy consumption is a common environmental policy. One mechanism used to achieve this is to encourage increased energy efficiency. However, improving efficiency may have an opposing effect and cause an increase in energy consumption if the intensity of use changes. This phenomenon is known as the rebound effect. We estimate direct rebound effects for energy use in Australia based on both aggregate residential energy use data and on household energy expenditure data. Our approach implements a new methodology developed by Hunt and Ryan (2014, Catching on the rebound: Why price elasticities are generally inappropriate measures of rebound effects. Surrey Energy Economics Discussion Paper Series SEEDS 148; 2015, Energy Economics 50, 273) that explicitly relates energy service use with energy source demand and directly incorporates measures of efficiency changes. The results indicate that the rebound effect is relatively high for energy use by Australian households. Due to the unique nature of our household data set, we can examine the influence of demographic and housing characteristics. We find that low‐income households and households with vulnerable members have the largest rebound effects. The relatively large rebound effects found here suggest that consumers gain from efficiency by improved energy services, and thus, policy targeting energy efficiency is not likely to be successful at reducing energy consumption.  相似文献

湖南省农业生态与农业经济耦合性测度   总被引:3,自引:0,他引:3  
[目的]考察湖南省近9年来农业生态与农业经济系统耦合发展现状,探究二者发展过程中的规律,以期找出二者协调发展模式,并为湖南省农业生态环境保护、农业经济发展提供决策依据。[方法]运用耦合协调度模型,基于熵权法为各指标进行客观确定权重,结合2007~2015年湖南省农业生态与农业经济发展的相关数据,确定农业生态与农业经济的耦合匹配分析模型,采用熵值赋权法确定各项指标的权重,构建农业生态—农业经济耦合协调评价指标体系。[结果]研究结果表明,2007~2015年湖南省农业生态与农业经济的耦合协调发展基本稳定,耦合度值均在0.9以上,二者呈协调发展趋势。其中,2014年和2015年二者的耦合度较高,分别为0.975 3和0.984 3,说明湖南省在这两年的农业生态与农业经济的协调性好,农业经济与农业生态能够相互有效促进彼此的发展。同时,仍需时刻关注生态环境的承载力,降低对自然资源的无序攫取,实现经济的可持续发展。  相似文献

This paper enquires the dynamics of current account and capital account in Sri Lanka for the period 2001:Q1 to 2016:Q1 and also examines the role of some policy variables such as exchange rate and interest rate in this dynamics. Estimated autoregressive distributed lag (ARDL) bound testing approach to cointegration followed by error correction representation of the ARDL model have found that current account is caused by capital account and exchange rate, where capital account causes to produce a deficit in current account. In the dynamic adjustment of current account due to exchange rate, an evidence of J-curve phenomenon is noticed. Capital account is neither caused by current account nor by exchange rate but interest rate has a positive impact on it. Robustness of these findings is testified by the vector autoregression model, Wald test of Granger causality followed by an impulse response analysis and a variance decomposition analysis. These analyses, in addition, establish a negative impact of interest rate on current account. With the best of knowledge this is the first study that reveals the dynamics of current and capital account of Sri Lanka. Such a dynamics is critical from the policy perspective. Policy makers should caution before capital account liberalization.  相似文献

We study a tug-of-war game between two players using the lottery contest success function (CSF) and a quadratic cost (of effort) function. We construct a pure strategy symmetric Markov perfect equilibrium of this game, show that it is unique, and provide closed-form solutions for equilibrium strategies and values. In stark contrast to a model of tug-of-war with an all-pay auction CSF, players exert positive efforts until the very last battle in this equilibrium. We deliver a set of empirically appealing results on effort dynamics.  相似文献
